The intelligent PID adjuster is used in conjunction with all kinds of sensors and transmitters to realize the measurement and display of physical quantities such as temperature, pressure, liquid level, capacity, force, intelligent PID regulator, and PID adjustment and control, alarm control, data acquisition and recording of electric heating equipment, electromagnetic, electric and pneumatic valves with various actuators.

Functional characteristics

Universal input function
Automatic calibration and manual calibration function.
Manual / automatic no disturbance switching function
Selection of positive / negative reactions suitable for heating or cooling.
Control output signal limit.
The intelligent PID regulator adopts the combination of fuzzy control theory and traditional PID control, so that the control process has the advantages of fast response, small overshoot and high steady-state accuracy, and has obvious control effect on large pure time delay objects which are difficult to control by conventional PID.
Intelligent PID regulator has added 30 stages of program control function.
